How do i charge a capasitor the right way?
I use a camera circuit to charge mine but it takes veery long time for many! Anyone know? I am talking about 300Volt 50-200 uF

I dont even know what uF is.. Could anyone tell me that too?

 

uf Stands for micro farad it is how you measure a capacitor.

 

A camera circuit is designed to be cheap. it uses a small capacitor that can charge from the circuit's low power in a few seconds and gives off enough light for a closeup picture in the dark.
Maybe your battery is dead.
Maybe your capacitor value (uF) is much higher than the one the circuit is designed to charge.
The higher is the value of the capacitor then the longer it takes to charge.
